Embodiments of the present disclosure disclose a system, apparatuses and methods for determining the right to speak. In the embodiments, each Secondary Protective Device (SPD) selects a Request to Send (RTS) sequence from a preconfigured RTS sequence set and sends the selected RTS sequence to a Primary Protective Device (PPD). The PPD chooses one RTS sequence from the RTS sequence sent by the SPDs and sends the chosen RTS sequence to all the SPDs and then each SPD determines whether the right to speak is obtained according to the RTS sequence from the PPD. The system, apparatuses and methods provided by the embodiments of the present disclosure ensure that the RTS sequences sent to the PPD by the SPDs are almost always different. Therefore the efficiency of determining the right to speak is greatly improved and the satisfaction of users is improved effectively.
